How to lock or secure pen drive

Sometimes we store data on pen drive that we do not want to share with our family, friends or colleague. But most of people do not care about pen drives too much. They just leave it here and there. But we forget that data stored on pen drive can easily be seen by anyone. We must use some software to lock/encrypt or make pen drives password protected.

Here is good a and free software that can do it: http://www.TrueCrypt.org

How it works??

TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).

Let’s suppose that there is an .avi video file stored on a TrueCrypt volume (therefore, the video file is entirely encrypted). The user provides the correct password (and/or keyfile) and mounts (opens) the TrueCrypt volume. When the user double clicks the icon of the video file, the operating system launches the application associated with the file type – typically a media player. The media player then begins loading a small initial portion of the video file from the TrueCrypt-encrypted volume to RAM (memory) in order to play it. While the portion is being loaded, TrueCrypt is automatically decrypting it (in RAM). The decrypted portion of the video (stored in RAM) is then played by the media player. While this portion is being played, the media player begins loading next small portion of the video file from the TrueCrypt-encrypted volume to RAM (memory) and the process repeats. This process is called on-the-fly encryption/decryption and it works for all file types, not only for video files.

g.asdafdgfgf.com is now u.asdafdgfgf.com

Every thing was ok in last month, but since last few days JS/Downloader.Agent virus is back again. Seems our network have still some infected computer or they are infected again.
This time this virus has changed it’s location from g.asdafdgfgf to u.asdafdgfgf.com.

While our cable operator is trying to find the machine which is infected with the virus I’m trying a trick which is working for me. Well it’s simple: just turned of Javascript option. It’s working for me. I’m using FireFox browser Avast antivirus (4.8 Home edition).

Here is how you can disable JavaScript in FireFox:
Tools =>option and then click on “Content” tab. Now uncheck Enable JavaScript.

Disable JavaScript in IE 7.x, 6.x, and 5.x

1. Open Internet Explorer.
2. Select Internet Options from the Tools menu.
3. In Internet Options dialog box select the Security tab.
4. Click Custom level button at bottom right. The Security settings dialog box will pop up.
5. Under Scripting category check Active Scripting, Allow paste options via script and Scripting of Java applets
6. Check radio boxes.
7. Click OK twice to close out.

Removing JS/Downloader.Agent virus

Don’t know how but my computer infected by a virus called JS/Downloader.Agent. When ever I was starting Internet explored, I was getting the warning message from AVG Antivirus. I deleted it several times but it was coming back in every 2/3 min. The virus was coming with .js or .htm extension and was storing in some sub folder of ‘temporary internet files’ folder.

Whole day I tried to find a way to remove the virus, deleted a all the files/cookies of temporary internet file. Scanned whole computer 3/4 times with AVG Antivirus and few other anti virus softwares and spyware removal tools and other tools found from Google. None of them worked.

Finally I found a tool named “SmitFraudFix” from here. I downloaded this tool and followed the instruction. After that I’ve not got any warning in last two days. Seems this tool is really capable to remove this JS/Downloader.Agent virus.

Please note that I am not asking you to use this tool, this is my personal experience, there may be exist a better tool to remove this JS/Downloader.Agent virus. But this what I found useful and shearing it here with you. If you can suggest me a better then this one then I will be very thank full to you.
